The average opening price is your opening price.

The average position price is, for example, calculated on the second trading day according to the settlement price of the previous trading day.

If you want to close your position, it must be the difference between the closing price and your opening price.

I wonder if this is clear.

Pure hand tour, hope to adopt!
